Title: Submergible motor type pump
Inventor: OKADA AKIHISA
IPC: F04D7/08
Filed: 1985-06-26
Abstract: PURPOSE:To prevent wear of an upper radial bearing by flowing the liquid discharged from an auxiliary impeller into a spacing between a motor casing and a motor frame which constitute a double cylinder and delivering the liquid to the upper part of a motor casing and further into the annular static-pressure chamber of an upper radial bearing. CONSTITUTION:When an auxiliary impeller 7 is turned by a pump shaft 3a, motor cooling liquid from a piping 11 is increased in its pressure by the auxiliary impeller 7 via a flow passage 15 and then flows into a motor casing 10b from a flow passage 7a. Part of the motor cooling liquid passes through a through-hole 16b which is made in the lover part of a motor frame 16, is delivered into an annular spacing 10d between the motor frame 16 and the motor casing 14, cools the external surface of the motor, and finally is poured from a through-hole 16c into the annular static-pressure chamber 18 located in the middle part of an upper radial bearing 9A. The upper radial bearing is provided with a function of a static-pressure bearing without increase in load of a thrust bearing, hence preventing wear of said upper radial bearing.

Abstract: PURPOSE:To enhance element isolation capability through the shield effect (a line of electric force is terminated to a conductive film and is not easily terminated to a semiconductor substrate at the bottom part of groove) by providing a conductive film grounded to the substrate within the groove provided for element isolation. CONSTITUTION:A groove, for example, in the depth of 0.6mum is formed to an element isolating region of a silicon substrate 31 and as a first insulation film, a plasma CVD SiO2 film 32, for example, is deposited in the thickness of 0.2mum. Next, the plasma CVD SiO2 film 32 is patterned in order to expose the substrate 31 at the specified part. Next, as the conductive film, a phosphorus-doped polycrystalline silicon film 33, for example, is left within the groove by the etch back. In this case, the ohmic contact between the substrate 31 and polycrystalline silicon film 33 can be attained at the area where the substrate 31 is exposed, and the polycrystalline silicon film 33 is grounded to the substrate 31. Next, as a second insulation film, the CVD SiO2 film 34, for example, is deposited in the thickness of 2mum on the entire part of it and the surface is flattened. Next, such film is etched by the RIE until the silicon substrate surface of element forming region is exposed, and the entire part of substrate is flattened.

Title: Transfer part guiding device
Inventor: HAYAMA HIROTADA
IPC: G03G15/20
Filed: 1987-06-01
Abstract: PURPOSE:To remove the inferiority of transfer and the slurring of transfer by switching a sheet guide to a position which commands the upper side of a usual sheet path from a transfer part to a fixing part with a switching means when a transfer sheet reaches a specified position this side of the fixing part. CONSTITUTION:The sheet guide 32 is supported to be able to move between a 1st position which is under the usual sheet path from the transfer part 24 to the fixing part 15 and a 2nd position which commands the upper side of the usual sheet path and where the transfer sheet 26 which is going to pass the usual sheet path is raised in order to be folded to a surface side in the rear of a transfer position. Until the transfer sheet 26 enters the fixing part 15 from the specified position before the fixing part 15, the sheet guide 32 is switched from the 1st position to the 2nd position. By raising by the sheet guide 32, the transfer sheet 26 can be prevented from separating from a sensitive drum 6. Thus, the slurring of transfer and the inferiority of transfer are not caused.

     CONSTITUTION: Webs 32 and 33 of two, upper and lower, stages are led to drag rollers 36 and 37 by way of guide rollers 34 and 35. The upper stage web 32 is cut into halves in the width direction by means of a slitter 38. Respective halved webs 40 and 43 are deflected in opposite directions by turn bars 41 and 44. Thereafter, the webs 40 and 43 are led to a nipping roller 45 via guide rollers 46 and 47, and overlapped in two-floded state and then led to a folding cylinder 48. On the other hand, the lower stage web 33 reaches 3 former 52 from a drag roller 51 and is half- folded in the width direction, thereafter being led to the folding cylinder 48. Upon this occasion, both webs are cut in a predetermined length by a cutting cylinder 53, and half-folded by the folding cylinder 48 in the longitudinal direction, and clamped by a clamping drum 54 to be formed into folded papers 55 and 56.

Title: Slip control device for vehicle
Inventor: KAGEYAMA FUMIO
IPC: B60T8/70
Filed: 1991-06-11
Abstract: PURPOSE:To lower the slip value of each driving wheel at the time of starting initial slip while brake fluid pressure is being prevented from being frequently switched by shifting control from pressure increasing/decreasing phase to pressure increasing one when the acceleration of each driving wheel is higher than reference acceleration, and thereby executing the differential control of brake fluid. CONSTITUTION:A device is provided with a braking force control means 51 controlling the braking force of each driving wheel with brake fluid controlled, an acceleration detecting means 52 detecting the acceleration of each driving wheel, and with a judging means 53 judging whether or not acceleration detected by the acceleration detecting means 52 is higher than reference acceleration set in advance. When it is judged by the judging means 53 that the acceleration of each driving wheel is higher than reference acceleration in a state that pressure increasing/decreasing phase control is assumed by the braking force control means 51, the braking force control means 51 is allowed to be shifted in control from pressure increasing/decreasing phase to pressure increasing phase.

Title: Fuel inlet
Inventor: YAMAMOTO SEIJI
IPC: B60K15/04
Filed: 1994-06-21
Abstract: PURPOSE:To provide a fuel inlet which does not involve air exhausted from a fuel tank into fuel when fuel is injected. CONSTITUTION:When a valve element 16b is pressed by a tip of a gasoline injection nozzle N, comes apart from a stopper 4c, and rotates in the arrow direction around an oscillating shaft 16a, this serves as a partition wall which partitions an opening 12a of an inlet pipe 12 from an opening 14a of a breather tube 14. Since air exhausted from the breather tube 14 into an inlet passage 4b passes a side of the gasoline injection nozzle N and is exhausted from a fuel inlet 8 to the outside, there is no possibility of mixing the air with fuel which is blown out from a jet port S at a tip of the gasoline injection nozzle N. Thus, since it is possible to prevent air exhausted from a fuel tank from being involved into gasoline when gasoline is injected, the worsening of fuel supply efficiency is prevented, and furthermore the mixing of air bubbles with gasoline in the fuel tank is prevented.
